A method, computer program product and processor for quantitatively registering a 2D endoscopic ROI in a 3D volumetric imaging dataset. An endoscopic dataset and a volumetric imaging are registered to a common coordinate system. A 2D endoscopic ROI is generated within the endoscopic imaging dataset. A 3D surface ROI is generated within the volumetric imaging dataset corresponding to the 2D endoscopic ROI, based on a projection of the 2D endoscopic ROI to the registered common coordinate system.

L'invention concerne un procédé, un produit programme informatique et un processeur destiné à enregistrer quantitativement un ROI endoscopique 2D dans un ensemble de données volumétriques 3D. Un ensemble de données volumétriques et une imagerie volumétrique sont enregistrés dans un système de coordonnées commun. Un ROI endoscopique 2D est généré à l'intérieur d'un ensemble de données d'imagerie. Un ROI de surface 3D est généré à l'intérieur de l'ensemble de données d'imagerie volumétriques correspondant au ROI endoscopique 2D, en fonction d'une projection du ROI endoscopique 2D sur le système de coordonnées commun enregistré.
